Abstract: A system for controlling one or more motorized windows. The motorized windows each have a processor, a network device and wireless transmitters enabling connection via a network. The network is controlled by one or more mobile devices which receive user input. The mobile devices wirelessly connect to a local area network (LAN) via a hub. One or more hubs are connected via the LAN. The motorized windows are networked via a personal area network (PAN). The hubs convert the LAN protocol to the PAN protocol. Sensors send sensor data along with real time weather data to the processor. The processor uses this sensor data to update charts and schedules in memory, then sends commands to the controller based on these updated charts and schedules according to user defined and factory set parameters. The system includes both local and cloud-based control.

Abstract: The system includes a headrail, which includes a motor, a gearbox, and one or more tiltable slats. At least one slat includes sliding tracks. The system further includes one or more PV cells movably disposed within the sliding tracks. The PV cells slide in move along the tracks with regard to an amount of sunlight incident on the cells. Methods of operating a solar powered window covering are also disclosed. The methods generally include detecting a tilt of at least one window covering slat. The slat includes one or more PV cells disposed in sliding tracks in the slat, and the tilt indicates an amount of sunlight incident on the cells. The methods also include sliding the PV cells in the tracks with regard to the amount of sunlight incident on the cells.

Abstract: The invention is a motorized gearbox assembly. The motorized gearbox assembly includes a motor that drives an output shaft. The output shaft actuates a window covering by applying torque to a tilt rod of the window covering. The output shaft extends substantially an entire length of the motorized gearbox assembly. It also has a through-channel that extends substantially an entire length of the output shaft, so that the tilt rod can pass entirely through the motorized gearbox assembly. Because of this, the motorized gearbox assembly can be used for retrofitting blinds. In some embodiments, the motorized gearbox assembly has a diametrically polarized magnet driven by the output shaft, and a position encoder that measures the output shaft's position and number of rotations.

Abstract: In various example embodiments, a low energy electric motor brake is described comprising one or more electronic switches that connect the input wires to an electric motor together, thus shorting out the motor and braking the motor. The electronic switches are separate from the control system, and provide the braking function. This alleviates the motor controllers and other system control units from providing the braking function to the motor. The electronic switches require minimal to no power in order to maintain the brake to the motor. The control unit may be placed in a low power or sleep mode while the electronic switches maintain the brake.

Abstract: An apparatus includes a drum to draw in or let out a line and a motor and transmission coupled to the drum to apply a torque thereto. An encoder is provided to measure an angular position of the drum. A counter is provided to record a number of rotations of the drum. A locking mechanism automatically prevents rotation of the drum when the drum stops. Using this information, a processor may calculate an amount of line let out from the drum based on the number of rotations of the drum, the angular position of the drum, and a radius of the drum. In certain embodiments, the angular position and/or number of rotations is stored in non-volatile memory so that is can be recovered in the event of a power outage or other significant event.

Abstract: A system to reduce drafts in front of a window is described. The system includes a window covering and a motor and gearbox that adjust the window covering. The system also includes a first temperature sensor, a second temperature sensor, and a microcontroller networked to the motor and temperature sensors. The first temperature sensor is positioned above the window covering within a thermal convection zone of a window associated with the window covering, and the second temperature sensor is positioned below the window covering within the thermal convection zone. The microcontroller instructs the motor to adjust the window covering based on a temperature gradient from the first temperature sensor to the second temperature sensor.

Abstract: An apparatus includes a drum to draw in or let out a line and a motor and transmission coupled to the drum to apply a torque thereto. A tracking module tracks an actual amount of line let out from the drum. A servo control unit receives the actual amount, compares the actual amount to a desired amount of line to let out from the drum, and generates an error signal reflecting a difference between the actual amount and the desired amount. A modulation module generates, from the error signal, a control signal to control the motor, thereby bringing the actual amount into better alignment with the desired amount.

By contrast, the power electronics may include higher power electronics needed to receive power and drive the motor.

Abstract: An apparatus for automating a set of window blinds is described. The apparatus includes a motor and a microcontroller. The motor includes a window blind coupler that couples a window blind tilt rod to the motor. The microcontroller stores instructions that, when executed, instruct the microcontroller to dynamically actuate the window blind coupler via the motor. The instructions include obtaining a desired room temperature, calculating a first temperature gradient between the window-side of the window blinds and the room-side of the window blinds based on a window-side temperature and a room-side temperature, and calculating a second temperature gradient between the room-side temperature and the desired temperature. The instructions further include retrieving a tilted state related to the first temperature gradient, the desired room temperature, and a zero-value second temperature gradient, and activating the motor to turn the window blind coupler to tilt the window blinds to the tilted state.
